abstract background: transcranial doppler ultrasonography results have not been previously studied in among iranian sickle cell anemia patients. the present study was performed to evaluate the pattern of intracranial flow velocities among iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial art...

background: sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. the purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. methods: a cross-sectional study was conducted among the sickle cell patients atten...

background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...

background: sickle-cell anemia is characterized by defective hemoglobin synthesis with production of sickle hemoglobin. sickle red blood cells become deformed and rigid with difficulty to pass through narrow capillaries and frequent clotting and thrombosis leading to repetitive vascular occlusions and progressive organ damage. we conducted this work to study some adrenal functions using acth st...

Background: There are many parameters that modulate the severity of sickle cell anemia. Fetal hemoglobin (Hb F) is one of these major variables. However, its effect is clinically inconsistent. We conducted a descriptive study to assess the influence of Hb F on clinical events and hematological variables in patients with sickle cell anemia. Methods: 151 patients with sickle cell anemia with a st...

background: the aim of the present study was application of haemoglobin absorption spectroscopy as a distinguishing tool for identification of two haemoglobin types-hba and hbs. material and methods: millimolar absorptivities of normal adult haemoglobin (hba) and sickle cell haemoglobin (hbs) were monitored at ph values of 7.2 and 5.0, within the ultra violet and visible spectral range (250-650...

conclusions ultimately, we can conclude that the hemoglobin level at the time of admission and before delivery, the type of disease, gestational age, and transfusion could be effective factors of patient mortality. results the mean maternal age was 27.60 ± 6.37 years. the hemoglobin level at hospital admission was 8.9 ± 1.61 g/dl for the survivors and 7.73 ± 1.19 g/dl for the deceased patients ...

In patients with sickle cell disease, thrombotic microangiopathy is a rare complication. Also in sickle cell disease, intracardiac thrombus formation without structural heart diseases or atrial arrhythmias is a rare phenomenon. We herein describe a 22-year-old woman, who was a known case of sickle cell-βthalassemia, had a history of recent missed abortion, and was admitted with a vaso-occlusive...
